1. Structure of Metallurgical Coke of The Coke Breeze of 3--6mm Description：

Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.

Now is low and coke coke prices are losing money, so the price will is not strong.After coke enterprises, according to the area where the price reduction, coking plant shipments did not have obvious improvement, the downstream steel receiving still light, lead to coking plant inventory increase slightly.Above all, expected short-term domestic coke market weak downward is given priority to, but not drop too much.

5. FAQ

As the global financial crisis, decline in coal prices significantly, and although domestic coal prices fell, but the price is still higher than the international coal market, this can make China's coal market supply and demand will further change.

Q:I don't understand. With coke, then the rest of the coke, they are selling it?: According to the use of coal can be divided into: injection coal, coal, coal coking coal can be divided into: lean coal, coking coal, gas coal, fat coal, lignite in five categories. Coking coal is used to refine coke. The power plant's coal coal power coal can also be said that under normal circumstances, can not be used for coking coal can be used to make electricity.

Q:What is the essential difference between coal and coke?: (1) power coal(2) coking coal (bituminous coal)(3) coal used in coal chemical industry, which mainly includes gasification coal, coal for low temperature carbonization, hydrogenation of liquefied coal and so on.

Q:The difference between coal and coke: The production of coke products in general is mainly based on high temperature carbonization, and the carbonization temperature usually needs about 1000 degrees celsius. After years of development, the current large-scale coke furnace equipment and technology is relatively mature, have equipment to improve the yield so as to achieve large-scale production conditions, coke furnace built in recent years, each with a yield of about 500 thousand tons, the highest can be even more than 1 million tons / year, such as the recent launch of mine international coking plant two chamber coke oven 7.63 m, each with a yield of 1 million 100 thousand tons per year.

Q:The sulfur content of coal and coke in general, the coking process of sulfur content of coal into the output of sulfur content of coke compared to those who are high and low?: 80% to 90% of the sulfur in coal into coke, the other into the coke oven gas.

Q:How to determine the maturity of coke or not?: The degree of fragmentation of coke: refers to the different levels of coke accounted for the percentage of total coke production. The particle size of coke is very important in blast furnace smelting. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.Breaking strength of metallurgical coke (M40 drum index)The breaking strength of metallurgical coke is an index to reflect the breaking resistance of coke.Wear resistance of metallurgical coke (M10 drum index)The wear resistance of metallurgical coke is an index to reflect the wear resistance of coke.

Q:Coke belongs to the coal industry: Warehousing and postal 03 animal husbandry 26 chemical raw materials and chemical products 51 railway transportation 04 fishery 261 other chemical materials 52 road transport 05 Agriculture Forestry Animal Husbandry and fishery service 262 fertilizer 53 city public transportation B mining 263 pesticides 54 Water Transport 06 coal mining and washing industry 264 coatings, printing ink, pigment and similar products 55 air transport 07 oil and gas pipeline transport 08 5600 265 synthetic materials of ferrous metal ores 266 special chemical products 57 loading and unloading and other transport 09 non-ferrous metal mining 267 daily chemical products 5710 handling 10 non metal mining 27 medicine manufacturing 5720 transport agency services

Q:What is coke? What is the use?: In addition to coke for iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, its quality requirements vary. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength. But requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.

Q:Why does Coke provide heat when it is fired, it reacts only at high temperatures and why it is needed to provide heat?Which is the exothermic reaction, carbon dioxide or carbon monoxide?: Yes；To restore the Fe reaction to provide heat, this reaction requires a higher heat, but the heat is high, the heat is not high enough to provide; so adding coke, more convenient to raise the temperature;

Q:8 points will be isolated from the air to enhance the heat of coal, in addition to the main coke, but also the material listed in the following table: No.: Carbon containing ammonia, which belongs to the inorganic carbon monoxide; although contain carbon and inorganic nature but similar, belonging to the inorganic material, so the answer is: the 7;

Q:Why is coke used in blast furnace steelmaking?Why not use coal?: (2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.(3) the role of the skeleton: the blast furnace smelting process occurs in the movement and interaction between the rising of the gas and the falling of the charge. The pellets, coke, iron ore, ore and other materials according to a certain proportion, and batch sequence into a blast furnace, blast furnace smelting in reducing atmosphere under the hot metal, after providing to the steelmaking plant of the steel-making.
